Fainting after recent air travel could be a sign of pulmonary embolism (PE), a potentially fatal blockage in the lungs. Syncope or fainting is an uncommon symptom of pulmonary embolism; however, new research presented at CHEST 2012, the annual meeting of the American College of Chest Physicians (ACCP), found that fainting associated with recent air travel may be a key indicator for PE diagnosis. Fainting as a precursor to PE diagnosis was also associated with a saddle embolism, a larger and more life-threatening form of PE, as well as more abnormal ECG readings.

Early signs of lung cancer could be diagnosed using a simple blood test following a new discovery by scientists at the University of York.

Early detection of lung cancer has been shown to save lives, but available methods for screening at-risk people are either too costly or involve invasive procedures. The latest findings, published today in the US journal Proceedings of the National Academy of Sciences, mean that a simple blood test could now be developed. Dr Dawn Coverley, who is based at the University's Department of Biology and is funded by Yorkshire Cancer Research, has found that an altered form of a protein called Ciz1 is present in lung cancers, even when they are at a very early stage.

On 22 September 2012, the United Kingdom (UK) informed WHO of a case of acute respiratory syndrome with renal failure with travel history to the Kingdom of Saudi Arabia (KSA) and Qatar.

The FDA has approved a new treatment for people with worsening symptoms of severe chronic obstructive pulmonary disease (COPD), a lung disorder that makes breathing difficult.

The drug, roflumilast -- carrying the trade name Daliresp -- will be sold in pill form, unlike some other medications for COPD, which are inhaled.

The swine flu pandemic could trigger a spate of heart attacks if rates of illness surge as predicted this autumn, doctors warned.

Patients with heart disease are being advised to accept a vaccine against H1N1 swine flu as it becomes available next month in order to reduce the risk of fatal complications.

An estimated 5,200 people in England went down with the virus in the week before last compared with about 3,000 the previous week, suggesting that a predicted second wave of illness may be on its way.

Sir Liam Donaldson, the Chief Medical Officer, estimated that 19,000 people would die from the virus under the "worst case scenario", a significant drop from the figure of 65,000 given in July.

He said the revised estimations, calculated by Government scientists, were "assumptions and not predictions".

They are based on one in three people across Britain becoming infected, and do not take into account what impact the swine flu vaccine, due next month, will have.
